TYPE-WRITING MACHINE.

To all whom it may concern.-

Be it known that l, Henna): P. Moonnnns, citizen of the LT iiie-il ti'atcs, and resident of lVeel'iaivhen, in the county of Hudson and State of New Jersey, have invented certain 1]\\' and useful Improvements in Type- Vv riting" Machines, of which the following is a specification.

This invention relates to improvements in stopanechanism for arresting the rotation of the platen of a typewriting machine, such mechanism being especially useful in doing condensed billing and other-Work of similar character.

The invention consists of the features of construction, combinations and arrangements of parts which are hereinafter described and specified in the appended claims,

In the accompanying sheets of drawings, in which like reference numerals designate like parts in nifi'erent views, Figure l is a top and partly sectional view of mechanism embodying the inn ion, and fragments of;

a :dizOllillCl'l typeivriting machine including: a front sectional i a part of the platen; Fig: 2, elevation of said me hanism and of a fragmcnt of the platen and the left end of the platen frame, the section being taken on the line a-a:, Fi 1; Jig. 3, a perspective of a cam and lever; Fig. -l-, a detail vertical section taitcn on the line 2.e, i2, and viewed in the direction of the arrow at the right oil said line; parts h t; omitted and a piece being broken out of one of the parts shown; J '4'}, L l J1 4-? me left end or t- 5, an elevation of the platen-carriage and par" of said 1nechan ism; 6, a vertical section taken on the line y Fig. ft, and viewed in the direction the arrow at the right of said line; and 7, a rear view f the cam and shoivn in 8.

carriage or pla'tenframe are formed uides 9 and 10 which contain grooves 11 and 1'2 and which extend from the right end to the left end 1 3 of the platenfra1ne. The carriage is secured to the standards by means of anti-friction balls 14: and 15 which fit in the grooves in the rails and guides mentioned, the carriage being movable back and forth over the top plate 1. The platen shaft 16 extends through and has hearings in the ends of the platen-frame, and the platen 17 which is fast on the platen-shaft, has on its left end a line spacing Wheel 18 which is formed on the left head of the platen, this head. being affixed to the platen by screws 19.

In the upper part of the end 13 of the platen frame is a hearing 20 through which extends a sleeve 21. On this sleeve is mountt ed an arm 2-2 and to this arm is aivoted a 26 of a line spacing lever 27 extends through the sleeve 21 and on this shaft'is an arm 28 which tits in the recess 25 of the pawl 23. To the sleeve 21 is attached an arm 29 which extends downward from the sleeve 21 MR. shaft 26, and on the lower end of which is a spring pressed pin 30, which extends through a housing 31 on the arm 29 and into a recess in the end of the platen carriage. This arm is movable to a slight extent on the axis of the shaft 26 and may be locked by the pin 30 in. three di erent positions according to the distance through which it is desired to actuate the patvl 23. On the shaft 26 is a coiled spring 32 which tends to hold the line spaeii 2 lever, the pawl 23, and the parts operated a; the lever to actuate the pawl, in their normal positions. When the lever 27 is actuated the pawl 23 is moved into engagement with one of thetceth 18'"- of the line spacing wheel and the platen is rotated through a line-space distance, or tln-taigh distance corresponding to a one, two or three tooth movement of the line spacing Wheel, according to the position in which the arm 29 is locked to the platen frame. This line spacing mechanism is the same as that which is commonly used in the Monarch typewriting machine.

fOn the platen shaft next to the left head of the platen is mounted the device which is shown in perspective in Fig. 3, this device comprising a cam and lever t'ormed together and having a common hub 33 through w'hieia the platen shaft extends. A collar 34, which is fastened to the platen shaft bv a set screw 35, fits against the left face of this device. T he arm 36 of this lever extends normallv forward and upward from the platen-shaftshaft anti formdwells,

On the inner face of the end 13 of the platedfranie, near the guides 9 and 10, is a projection 41 inwhich is formed a bearing for a'ii u right shaft. 42. the lower end of this shaft is aliined. an a, m 43 which extends forward therefrom and on the front end of which is a roller 44, this roller being within the slot of the cam. In the upper end of the shaft 42 is fixed a spring45 which extends through a ,slot in the shaft and is secured therein by s,"'pin, 46 passing through the shaft and spring; The arm'43 and spring 45 bear against the ends of the projection or block 41 and so keepthe shaft in its proper position in its bearing; The s rin 45 extends from the shaft 42 forwar an then to the right and then forward'over the laten shaft, and has at its front end aroler 47 which is adapted'to engage the teeth of the line spacinggwheel 1 8. on this spring, and extending downward and tofthe left from the front porfion of the s ring,'is a clutch fork 48, thespring and for r being composed of a sin le piece of sheet metal. A member 49 ofa'c utch is mounted on the platen shaft next to the collar 34, this clutch menibcr having a grooved hub 50, into which the clutch fork 48"extends, and-beingjsplined to the platen shaft-by a spline 51 and being movable axially onthe platen shaft, This clutch member has teeth 52 formed on it, the being equal in number to the teeth 18* of the line spacing. wheel. At the left of the clutch member 49 a shoulder 53 is formed on the platen shaft 16, the portion 54 of the shaft at. c the left of this shoulder being smaller than.

the rest of. the shaft. On the part 54 of the platen shaft is loosely'mounted a disk 55, which bears against the shoulder 53, this disk having on ts right face teeth 56, adapted to be engaged by the teeth 52 of the-clutch member above mentioned, and on its left face a hub 57. 'A tongue 58, which constitutes a stop, is formed on or rigidly-attachedto this disk. Between the hub 57 ofthe disk just described and the end 13 of the platen-frame, is a disk 59 which is loosely mounted on the platen shaft and on the right face of which eth' is a projection or stop 60, which is fast on v the disk. In the left face of this disk is a series of round holes .61, arranged in-a circle at equal distances apart, there being as many of these holes as there are teeth 18 in the line spacing ratchet wheel, and on the end of the disk 59. This spring surrounds the hub 57 of the disk 55 and "is attached to each of these disks, the sprin being under tension ame is mounted a spring-pressedsk has a knurled edge 63 to i and tending to turn t e top of the disk 55 toward the back of the machine when the disk 59 is locked to the platen-frame. A stop 65, affixed by a screw 66 to the inner face of the end 13 of the platen frame, projects inward behind the disk 59, and is so arranged that the tongue 58 on the disk 55 will make contact withit. A finger wheel 67 is mounted on the left end of the platen shaft and secured thereto by a set screw 68 fitting in a threadcdhole in the hub of the finger wheel and extending into a recess in'the shaft. i v v When writing is being done on the may chine the parts of the mechanism described are in the positions in which they are shown in Figs. 1 and 2 of the drawings. The roller 44 on the arm 43 is then close to the upper end of the slot 40 inthe cam, and the roller 47 on the spring 45is ressed a ainst the line spacing wheel 18, t e parts locked inthese positions b the action of the dwell of the cam on the r01 er 44. The clutch member 49 is then held by the clutch fork 48 out of engagement with the disk 55.. the platenis turned by the line spacing lever or otherwise-the roller 47 is forced to the left by the action of the teeth of the line spacing wheel-upon it, against the ressure of thes ring 45, the spring and rol er 47 actin as oes the ordinary roller-detent of theibionarch machine. The groove in the hub 50 of the clutch member 49 is wide enough 0 allow the fork 48 to benio'vedtothe left y the spring, actuated. as 7 described by eing ratchet teeth, withoutimparting' motion to platen the angularmovement of the tongue i 58, in traveling frong the stop 65 to the stop 60, will be equal to t e angular moveme'ntof the platen required ,for feeding a sheet of paper into the machine to the position where Y it is desired to writethe firstline on the paper. The adjustment of the disk 59 11121) be changed by pulling out the pin 62, turnthe disk with the hand, and reengagmg the pin with he disk.

f .ihen the last entry has been made on a i "or example as a bill sheet, the e stop mechanism described being positions in which they are shown and 22, the finger piece37 of the Y pulled forward so that the roller ist is moved to the left by the action of the cam on this roller. spring is likewise moved to the left and the clutch fork forces the clutch member 49 into engagement with the teeth of the disk "1 the members of the'clutch being locked I); together by the action of the cam on the roller is, since the roller is then close to the lower end of the slot where it cotiperates with the other dwell of the cam. The platen is then rotatel backward by turning one of the linger wheels, and'the tongue or stop 58, which is then connected by the clutch to the platen shaft, travels from the stop to the stop 60 and when it reaches the latter stop the platen is arrested. This backward rotationof the platen is equal to the forward rotation required for feeding into the machine the nest bill or sheet and bringing it to a position to receive the first line of writing. The new sheet is then inserted in the machine and the platen is turned forward until it is arrested by the contact of the stop 58 with the fixed stop 65. The bill is then in such a position that the first line of writing will be at the proper distance from the top of the hill or sheet-.-

It will be observed that when the disk is clutched'to the platen shaft as described the roller 47 is out of engagement with the line spacing ratchet wheel and offers no resistance to the rotation of the platen.

As the clutch fork 48 is a part of the spring 4-5 it may be made to exert constant pressure on the clutch member 49, tending to keep it en t ed with the disk 55, while the parts from the particular form shown and desc Ibed herein.
